Magnetic Dipole Moment of a Neodymium Magnet The Experiment
... The dipole moment of a magnet has its origins in the motion if the electrons in the material. Electrons orbits a nucleus, for example, act somewhat like a current going round a tiny circular circuit. For a variety of reasons (mostly quantum mechanical) the dipole moment of an atom is rarely much big ...
